Laboratory classes are a central element of all biochemistry and molecular biology programs. These play a role in developing students' hands-on and technical skills and also offer much more. The design of laboratory classes depends on many factors including the programs the students are enrolled in, the level they are at, employment destinations,…

Social media are a highly visible factor in the daily lives of our students. Why should teachers not take advantage of this and develop teaching and learning materials that use the designs found in such media to contextualise science learning? This article suggests some ideas for creating lab instructions using social media design as an innovative…

An initial goal of chemistry laboratory courses is almost always the "proper" use of laboratory resources including glassware and instruments. The proper use of glassware encompasses many topics, such as laboratory safety, technical proficiency, and recognition of function. However, as many chemical educators can attest, at both the K-12 and…

In delivering chemistry courses by distance, a key challenge is to offer the learner an authentic and meaningful laboratory experience that still provides the rigour required to continue on in science. To satisfy this need, two distance general chemistry laboratory courses appropriate for Bachelor of Science (B.Sc.) students, including chemistry…

Engaging undergraduate students in designing and executing original research should not only be accompanied by technique training but also intentional instruction in the critical analysis and writing of scientific literature. The course described here takes a rigorous approach to scientific reading and writing using primary literature as the model…

A modification of the mixed-aldol synthesis of dibenzylideneacetone, prepared from acetone and benzaldehyde, is described wherein acetone is replaced with a series of cyclic ketones with ring sizes of 5-7 carbons. The structural variations in the resulting conjugated ketones produce regular variations in the UV-vis absorption spectra. The choice…

Despite being criticised for placing little emphasis on thinking, the majority of laboratory work at school level is taught "via" expository "recipe-style" labs. This has been seen to result in students struggling to be able to apply the practical techniques they have learnt in the classroom outside the narrow environment in which they were…
